fix non-portable use of grep and awk related to release date checks
Building gst-plugins-ugly-0.10.19 on x86_64-pc-solaris2.11 (OpenIndiana
oi151a8). I'm using the Oracle Studio 12.3 compiler suite, but this issue
isn't related to the compiler.
While configuring gst-plugins-ugly, I see
checking for GST_BASE... yes
checking for GST_CHECK... no
configure: No package 'gstreamer-check-0.10' found
configure: no gstreamer-check-0.10 >= 0.10.36 (GStreamer Check unittest
Library) found
checking for GST_PLUGINS_BASE... yes
configure: using GStreamer Base Plugins in /usr/lib/amd64/gstreamer-0.10
configure: Using /local/lib/64/gstreamer-0.10 as the plugin install location
grep: illegal option -- e
Usage: grep [-c|-l|-q] [-r|-R] -hbnsviw pattern file . . .
awk: syntax error near line 3
awk: illegal statement near line 3
awk: syntax error near line 4
awk: bailing out near line 4
configure: error: SET_PACKAGE_RELEASE_DATETIME: could not extract
release date for release version 0.10.19 from
"./gst-plugins-ugly.doap"
There are two issues here
1) common/m4/gst-package-release-datetime.m4 uses "grep -e" in a couple places.
That's not portable (traditional grep on UNIX systems doesn't accept a -e
option) and in this case it's also not needed. The regexes in use are simple
and do not require extended regular expression support (a la egrep), so
dropping the -e fixes the issue.
2) the common/extract-release-date-from-doap-file uses some non-portable
awk syntax:
$0 ~ "something"
isn't portable, but
$0 ~ /something/
would be.
Ultimately, I think it would be a better idea to use xsltproc (which is
required by pre-reqs of gstreamer, so you can safely assume it's going to be
present) and a small .xsl file to get the release date from the .doap file, but
that's a separate issue
A possible patch for the two portability issues is attached.
